Constructor Detail

IdealMagSolenoid

public IdealMagSolenoid(java.lang.String strId,
                        double dblFld,
                        double dblLen)

Creates a new instance of IdealMagSolenoid

Parameters:

strId - identifier for this IdealMagSolenoid object

dblFld - field gradient strength (in Tesla)

dblLen - length of the solenoid

IdealMagSolenoid

public IdealMagSolenoid()

JavaBean constructor - creates a new unitialized instance of IdealMagSolenoid BE CAREFUL

Method Detail

elapsedTime

public double elapsedTime(IProbe probe,
                          double dblLen)

Returns the time taken for the probe to drift through part of the element.

Specified by:

elapsedTime in interface IElement

Specified by:

elapsedTime in class Element

Parameters:

probe - propagating probe

dblLen - length of subsection to propagate through meters

Returns:

the elapsed time through sectionUnits: seconds

energyGain

public double energyGain(IProbe probe,
                         double dblLen)

Return the energy gain imparted to a particular probe. For an ideal solenoid magnet this value is always zero.

Specified by:

energyGain in interface IElement

Specified by:

energyGain in class ThickElement

Parameters:

probe - dummy argument

dblLen - dummy argument

Returns:

returns a zero value

transferMap

public PhaseMap transferMap(IProbe probe,
